阀座

2 For the low-pressure seal test and high pressure sealing test, does not allow visible leak through the valve flap, the back seat and shaft seal, there is no structural damage (elastic seat and seal surface deformation is not considered as structural damage).

3.9.2对于低压密封试验和高压密封试验，不允许有明显可见的泄漏通过阀瓣、阀座背面和轴密封，并无结构上的损坏(弹性阀座和密封面的塑性变形不作为结构上的损坏考虑)。

Ram sealing surface than the valve seat to seal a broad margin, and to ensure that the valve is not in use before the sealing of the bottom line and the gate valve seat bottom line sealing surface at the same level, so that the valve in the use of a certain period of time after not even wear Will reduce the need to ensure the sealing surface width.

闸板密封面比阀座密封面宽出一定的余量，并保证阀门在未使用前闸板密封面底线与阀座密封面底线在同一高度，使阀门在使用一定时间后即使磨损也不会减少必须保证的密封面宽度。

Seating - Buna N disc to metal seating assures positive seal for shutting off the gas to burner in the event of high water temperature conditions.

阀座 -丁腈橡胶阀瓣对金属阀座，确保在出现过高水情况下关闭通向燃烧头的燃气时的密封性。

The valves feature a replaceable abrasion resistant Chloroprene seat, a 304 stainless steel seat guided gate, and PTFE packing.

这种阀门配置可更换的耐磨损氯丁二烯阀座，304不锈钢阀座引导的闸板，以及PTFE密封填料。

Though there is no condensate water that uses ball-type sealed lever to make the valve clack tightly adhesion to the valve seat, it can prevent the fresh vapor from leakage.

阀座孔设计在凝结水水位以下，自然形成水封，水、汽自然分离，达到无蒸汽泄漏，即便没有凝结水采用球型密封的杠杆使得阀瓣紧贴阀座，达到无新鲜蒸汽的泄漏。

Metal cock ring soft seat surface pressure to the bearing surfaces, such as the valve core and valve seat is concentric ring surface can be a double tight closure.

金属旋塞表面压向阀座环软支座表面，如阀芯和阀座环表面是同心的，就能得到双重严密的关闭。

Through valve: A valve with a linear movement of the closure components, there is a single seat or multi-seat, and its valve seat area because there is a spherical cavity and different.

直通阀：一种阀门，带线性运动的截流元件，有单阀座或多阀座，它的阀体因为阀座区域有一个球形的内腔而与众不同。

The pressure of the medium act against the two valve seats equally in reverse direction, so the pressure on the valve seat is offset, the valve core assumes relatively low pressure when the valve is open, in this way the overlarge displacement is obtained.

双平衡阀座：该阀利用双阀孔设计，介质的压力对两个阀座作用相等，方向相反，介质压力对阀座作用相抵消，阀芯在开阀时压力相对减少，从而获得超大排量。

Mechanical-type steam trap pressure drop by different paragraphs, divided into a variety of specifications of the valve seat aperture "No. Seat", each of the above pressure and "its seat" of a curve of the displacement of coordinates, different "seat No."The thinning of water are very different.

机械型疏水阀按不同的工作压差段，分成多种规格阀座孔径的&阀座号&，每个工作压差段与&阀座号&组成一条坐标曲线的排水量，不同&阀座号&的疏水量有很大差别。

Mechanical-type steam trap pressure drop by different paragraphs, divided into a variety of specifications of the valve seat aperture "No. Seat", each of the above pressure and "its seat" of a curve of the displacement of coordinates, different "seat No."The thinning of water are very different.

机械型疏水阀按不同的事情压差段，分成多种规格阀座孔径的&阀座号&，每个事情压差段与&阀座号&构成一条坐标曲线的排水量，不同&阀座号&的疏水量有很大差别。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
